there is a site that has pictures of multiple cabins on all of the ships.

they may not have your specific cabin, but something near it or on a different deck. most cabins are very similar on a specific ship. the largest differences are Suites, Junior suites, and handicap accessible.
Go to youtube and look, you might no find your cabin but will find the same type of cabin. I have done this in the past and it's really kind of fun to watch the videos.
Thank you I did find some videos of rooms that should be like ours Now I am even more excited for our ocean view room. My son is just worried the couch won't be good sleeping. I told him I am sure it will be though.
